Īll dates are in relation to the Conquest of Aegon I Targaryen, using negative numbers for events before Aegon's Conquest. Martin is sometimes intentionally imprecise with dates or distances. The accuracy of the legends and myths that recount much of this history is openly questioned by the maesters of the Citadel, amongst others. Everything written about the Age of Heroes, the Dawn Age, and the Long Night originates from stories written down by septons thousands of years later. However, the oldest historic recounts in Westeros were written after the Andals' arrival to the continent, as the First Men used runes for carving on stone.

For further detail, see years before Aegon's Conquest and years after Aegon's Conquest.Īccording to tradition, the known history of Westeros extends back over twelve thousand years, and its maesters speculate that the world itself may be forty thousand years old (or older, possibly five hundred thousand years or more). This timeline of major events attempts to lay out the most important points in the history of Westeros and Essos, based on dates and information given in the novels and supporting material.
